1) I feel like the primary images on pages should be the images of the bird from the menu screen.
2) You are missing pages such as the Griffin, Owl, Emu, Albatross or Pelican.
3) The pages need to be longer. I think more information should be added.
4) There are no pages for maps whatsoever.
5) There are no pages with infoboxes. I’d recommend using infoxboxes to give a quick summary of the page topic.
I’m pretty sure this wiki is dead and there’s no fixing it, but if it comes back, keep this in mind.
